Evaluate the expression √−7/√ −6√−5 and write the result in the form a+bi.
I keep getting b as 0.483i but apparently its wrong?
Well, you need to work on using parentheses
√−7/√−6√−5 means (√−7/√−6)(√−5)
= 7i/6i * 5i
= 35/6 i = 5.83i
√−7/(√−6√−5) = 7i/-30 = -0.233i
0.483 = 29/60
Too bad you didn't bother to show your work, eh?
Or is there a typo in the problem?posted by Steve
